Get domain from uri

[Ryan Chan]

Hello,

I want to get the domain from uri, e.g.

http://www.example.com/index.html => example.com
http://foo.example.com/index.html => example.com
http://foo.example.co.uk/index.html => example.co.uk
http://foo.example.company.com => company.com
http://foo.example.company.com.hk => company.com.hk

It seems that URI module does not have this feature yet, any
recommendation?

Thanks.

What are the criteria for whether you go 2- or 3-deep to
get what you consider to be the domain?

Think about Alexa, they map subdomains (with many level) into a single
domain and generate the ranking

e.g.

http://uk.finance.yahoo.com => yahoo.com


What I want to do is something like that.

As it stands, there doesn't seem to be a purely syntactic
solution, you'll need knowledge of how each TLD is
organized.

Oh, I would totally have missed the original question, if it wasn't for
this reply.

I found this:

Net:omain::TLD
http://search.cpan.org/perldoc?Net::Domain::TLD

which is a module to reduce a domain name to its core domain name.

No it's not. It gives you a list of valid TLDs, which is not the same.

You seem to be right... It was wishful thinking on my side.
